I need to identify key qualities of drama and poetry which emphasize their performative qualities. Can you help?

The three genres of “poetry” identified by the Greeks are Epic, Lyric, and Dramatic – they differ by narrator (lyric has one, drama has none, and epic has many narrators). In the process of “performing” these genres, emphasis is placed on the imitative nature of narration. Drama is primary “speech acts” (the performing of acts by using language – promise, deny, warn, etc.) and the performative element comes into play when the narration takes on a personification through stage language – posture, gesture, blocking, costume, etc. – Poetry (or , technically, verse) gets its performative qualities from the single narrator imitating the action of having the emotion (joy, sorrow, etc.) of the sentiment. The hearer or witness to the performative acts then identifies that emotion and engages with the mise-en-scene through imagination. A fairly recent discipline, performance theory (see Richard Schnechner) digests this information and supplies a vocabulary for critical discussion. It is partly an artistic endeavor and partly a sociological inquiry into the way we perform our rhetorical agency.)
